EGG- GRADER 0R SCALE.

Application led October 4, 1920. Serial No. 414,555.V

To all whom it may concern:

Be it known that I, RUrUs V. B. LINCOLN, a citizen of the United States, residing at Escondido, in the county of San Diego andl State of California, have invented a new and useful Egg Grader or Scales, of whichv the following is a specification.

My invention has for its object a simple,

l durable, and eiiicient device for use by poultrymen and others in grading eggs, and designed especially for grading eggs by weight into three diflerent sizes, namely, thosethat weigh less than eighteen ounces per dozen and which are known on the market as peewee pallets; those that weight betweeneighteen and twenty-two ounces per dozen commonly known as pullets, and those that weigh more than twenty-two ounces perA dozen known as standard eggs.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing in which is shown a preferred embodiment of my invention, and in which Fig. 1 is a side elevation of the device partly in section, and Fig. 2 is a top plan View thereof.

Corresponding and like parts are referredv to in the following description and designated in both views Aby like reference numerals.

Referring to the drawing, the numeral l designates a beam or bar which is preferably composed of a metal or other plate formed with side flanges 2 and provided near one end with an opening 3 in which the eggs are intended to be placed .one at a time, for the purpose of being weighed.

The principal feature of n1 improved egg grading device is comprise in the provision of two fulcrun'ls 4 and 5 which, 1n the present embodiment of the invention illus- .trated in the accompanying drawing, are

formed as downward projections integral with. 'the side flanges 2. It will be understood that there is a pair of fulcrums 4 disposed in transverse alinement vwith each other, one formed on each side lange'Q and a corresponding pair of fulcrum polnts 5, and it is to be particularly noted that both fulcrums 4 and 5 are disposed to one side of the transverse balancing axis of the beam l. That is to say, ythe fulcrum 4l and theI fulcrum 5 are both so disposed that in the normal position of the beam l it will be out of balance, so to speak, and rest 1n the inclined the longer end resting upon the supporting surface and'with the shorter end, with the opening 3 formed in it, inelevated relation to such surface. i

In-the practical use of the device the eggs are placed one at a time, preferably on their butt ends, in the somewhat countersunk or rimmed opening 3. if the position of the beam resting as illustrated in Fig. 1, is not disturbed or changed, the egg weighs 'less than eighteen ounces per dozen andfalls in the peewee grade; if the beam l be so tilted by the weight of the egg in the opening 3 as to rest upon the two fulcrums 4 and 5 jointly, theegg weighs between eighteen and twenty-two ounces per dozen and be* longs in the pullet grade; and if the weight o the egg tilts the beam of the grader Iso as to cause it to rest on the left hand fulcrum 4 alone, the egg weighs more than twentytwo ounces per ldozen `and belongs in the standard grade.

F rom the foregoing4 description in connection with the accompanying drawing, it will be seen that I have Lprovided a very simple and durable and e icient egg grading device which can be very cheaply manufactured and which may be used with considerable facility to quickly grade eggs into different commercial grades or sizes.

, l/Vhile the accompanying drawing illusposition illustrated in Fig. l with y trates what I believe to be the preferred embodiment of my device, it is to be understood that the invention is not limited thereto but that slight changes may be made in the construction, design, and proportions of the parts without departing from the scope of the invention as defined in the appended claim. f I

Having thus described the invention what I claim as new, is: l

As a new article of manufacture, the herein described egg grader comprising a beam formed near one end with -means for supporting an egg thereon and near said end with a lurali'ty of fulcrums arranged in longitudlnally spaced relation to each other, said fulcrums being located to one side of the transverse balancing axis of said beam whereby in the normal position of the device the beam will rest on the fulcrum which is farthest away from the egg supporting means.
